Question 140

A proposed decision is challenged in the following case: Several business units claim authority over enterprise architecture with no agreed skills or accountability. Which misleading belief must be rejected?

  1. Phase E's only output is a final postdeployment compliance report.
  2. Phase H exists only to manage help-desk incidents unrelated to enterprise strategy.
  3. A network connectivity diagram alone establishes resilience and disaster recovery readiness.
  4. Architecture staffing is outside the scope of establishing an EA capability.

Explanation

Correct Answer

D:

This is precisely the false assumption to challenge for Preliminary organizational model. The governing principle is: The EA capability includes people, roles, organizational relationships, skills, and governance arrangements.

Incorrect Answers

A:

The shortcut would be dangerous for Phase E solution options; it is not the particular misconception driving the described Preliminary organizational model situation (Several business units claim authority over enterprise architecture with no agreed skills or accountability).

B:

This false belief is about Phase H change trigger. The central misconception is that architecture staffing is outside the scope of establishing an EA capability.

C:

This is also a risky claim, but it directly concerns Phase D resilience rather than the error in the current case: Several business units claim authority over enterprise architecture with no agreed skills or accountability.

Question 141

Consider this enterprise-change situation: After a merger, architects duplicate work because the architecture team's scope and organization were never settled. What is the most appropriate architecture action?

  1. Define the architecture organization, responsibility boundaries, and required capabilities in the Preliminary Phase.
  2. Model Application Architecture components, services, and their required interactions.
  3. Use Phase E Opportunities and Solutions to assess candidate solutions and identify meaningful work packages.
  4. Use continuous Requirements Management to baseline, assess impact, resolve conflicts, and update traceability.

Explanation

Correct Answer

A:

This directly addresses Preliminary organizational model. The EA capability includes people, roles, organizational relationships, skills, and governance arrangements. A useful acceptance check is: A responsibility model shows how architects, sponsors, and decision bodies collaborate. This matters here because after a merger, architects duplicate work because the architecture team's scope and organization were never settled.….

Incorrect Answers

B:

Although relevant to Phase C application collaboration, this is not the most direct response to Preliminary organizational model. For this decision, what matters is whether a responsibility model shows how architects, sponsors, and decision bodies collaborate.

C:

This action targets another architecture concern: Phase E solution options. The priority here is Preliminary organizational model in this situation (After a merger, architects duplicate work because the architecture team's scope and organization were never settled); it leaves the specific acceptance result unaddressed: a responsibility model shows how architects, sponsors, and decision bodies collaborate.

D:

This proposal belongs primarily to Requirements management cycle. It does not show that a responsibility model shows how architects, sponsors, and decision bodies collaborate.

Question 142

During design review: After a merger, architects duplicate work because the architecture team's scope and organization were never settled. What is the strongest architectural reasoning for the decision?

  1. The Preliminary Phase prepares architecture work by establishing capability, governance, principles, and tailoring.
  2. The EA capability includes people, roles, organizational relationships, skills, and governance arrangements.
  3. A Transition Architecture is an architecturally meaningful intermediate state between baseline and target.
  4. Architecture Change Management monitors change drivers and maintains architecture relevance over time.

Explanation

Correct Answer

B:

This principle addresses Preliminary organizational model. The preferred action is: Define the architecture organization, responsibility boundaries, and required capabilities in the Preliminary Phase. Verify: A responsibility model shows how architects, sponsors, and decision bodies collaborate. This matters here because after a merger, architects duplicate work because the architecture team's scope and organization were never settled.….

Incorrect Answers

A:

This is a legitimate concept for Preliminary capability; it does not most directly account for After a merger, architects duplicate work because the architecture team's scope and organization were never settled. The important distinction is that the EA capability includes people, roles, organizational relationships, skills, and governance arrangements.

C:

That principle helps reason about Phase E transition states, but the described concern (After a merger, architects duplicate work because the architecture team's scope and organization were never settled) is specifically governed by Preliminary organizational model. It does not explain the EA capability includes people, roles, organizational relationships, skills, and governance arrangements.

D:

This is a legitimate concept for Phase H change trigger; it does not most directly account for After a merger, architects duplicate work because the architecture team's scope and organization were never settled. The important distinction is that the EA capability includes people, roles, organizational relationships, skills, and governance arrangements.

Question 143

Following the proposed architecture change: After a merger, architects duplicate work because the architecture team's scope and organization were never settled. Which outcome should be verified?

  1. Affected activities have named actors, role ownership, and defined handoffs.
  2. An approved capability charter identifies roles, governance, adapted method, and operational support.
  3. A responsibility model shows how architects, sponsors, and decision bodies collaborate.
  4. Each intermediate state has clear capabilities, dependencies, and an eventual target relationship.

Explanation

Correct Answer

C:

This checks the Preliminary organizational model outcome. The related decision is: Define the architecture organization, responsibility boundaries, and required capabilities in the Preliminary Phase. This matters here because following the proposed architecture change: After a merger, architects duplicate work because the architecture….

Incorrect Answers

A:

This result checks another area, Phase B stakeholder roles. For This case (After a merger, architects duplicate work because the architecture team's scope and organization were never settled), it does not establish that a responsibility model shows how architects, sponsors, and decision bodies collaborate.

B:

This would provide assurance for Preliminary capability, not the stated issue (After a merger, architects duplicate work because the architecture team's scope and organization were never settled). It does not show a responsibility model shows how architects, sponsors, and decision bodies collaborate.

D:

This result checks another area, Phase E transition states. For This case (After a merger, architects duplicate work because the architecture team's scope and organization were never settled), it does not establish that a responsibility model shows how architects, sponsors, and decision bodies collaborate.

Question 144

A proposed decision is challenged in the following case: After a merger, architects duplicate work because the architecture team's scope and organization were never settled. Which misleading belief must be rejected?

  1. An application list alone proves every required integration is implemented.
  2. Phase B is principally the selection of server operating systems.
  3. Prioritizing each project solely by its isolated ROI always yields an executable portfolio.
  4. Architecture staffing is outside the scope of establishing an EA capability.

Explanation

Correct Answer

D:

This is precisely the false assumption to challenge for Preliminary organizational model. The governing principle is: The EA capability includes people, roles, organizational relationships, skills, and governance arrangements. This matters here because a proposed decision is challenged in the following case: After a merger, architects duplicate work because the….

Incorrect Answers

A:

This is also a risky claim, but it directly concerns Phase C application collaboration rather than the error in the current case: After a merger, architects duplicate work because the architecture team's scope and organization were never settled.

B:

The shortcut would be dangerous for Phase B business baseline; it is not the particular misconception driving the described Preliminary organizational model situation (After a merger, architects duplicate work because the architecture team's scope and organization were never settled).

C:

This false belief is about Phase F benefit dependencies. The central misconception is that architecture staffing is outside the scope of establishing an EA capability.

Question 145

Consider this enterprise-change situation: The enterprise architecture function starts work without agreed decision rules for reuse and interoperability. What is the most appropriate architecture action?

  1. Develop and obtain agreement on enterprise architecture principles during capability setup.
  2. Review the Request for Architecture Work and establish the scope, constraints, and stakeholders for Phase A.
  3. Use Phase E Opportunities and Solutions to assess candidate solutions and identify meaningful work packages.
  4. Define the architecture organization, responsibility boundaries, and required capabilities in the Preliminary Phase.
